Actuating the Link
The intended behavior for a link when activated by an application, specifically, the timing for obtaining or retrieving the content of a link (for example, by a user clicking on the link to request the material, or by the material being automatically loaded with a document when the document or document component is loaded).

<abbrev>, <article-version>, <award-group>, <award-id>, <bio>, <chem-struct>, <collab>, <conference>, <contrib>, <custom-meta>, <element-citation>, <email>, <ext-link>, <funding-source>, <graphic>, <inline-graphic>, <inline-media>, <inline-supplementary-material>, <institution>, <issue-id>, <license>, <long-desc>, <media>, <mixed-citation>, <named-content>, <nlm-citation>, <product>, <pub-id>, <related-article>, <related-object>, <resource-name>, <self-uri>, <supplementary-material>, <support-source>, <uri>, <volume-id>
|none||The behavior is unconstrained, and no other markup is generally available in the link to assist an application in deducing the retrieval mechanism.|
|onLoad||An application should retrieve the link at the same time a user obtains the initial document.|
|onRequest||An application should only retrieve the link after a user has physically triggered the retrieval, for example, clicked on the link.|
|other||The behavior is unconstrained, but other markup is generally available in the link to assist an application in deducing the retrieval mechanism.|
